[1] After 1948, Communist authorities changed both the flag and the coat of arms.

The coat of arms became more emblematically faithful to Communist symbolism: a landscape (depicting a rising sun, a tractor and an oil drill) surrounded by stocks of wheat tied together with a cloth in the colors of the national flag.

The emblem shows a landscape with a fir-wood and the Carpathian Mountains, on the dexter a derrick and in the sky a rising sun all proper.

On the ears, were the wheat with the motto "RPR" in white lettering on a ribbon.

Some flags had a hole (a symbol of the revolution) and some changed to the later official blue-yellow-red format.
